Description

В строительной практике часто имеют место случаи, когда вблизи строительной площадки нет песка требуемого качества и его приходитс  доставл ть издалека. Это отражаетс  в значительной мере на увеличении стоимости строительства .In construction practice, there are often cases when there is no sand of the required quality near the construction site and it has to be delivered from a distance. This reflects to a large extent on the increase in construction costs.

В св зи с этим, автором насто щего изобретени  предлагаетс  способ укреплени  слабых песков, которые почти всегда имеютс  на месте , в районе строительной площадки , в виде грунтового песка и И отбросов разработок известн ковых и т. п. слабых каменных пород. Так, -например, в районе Баканских винохранилищ были обнаружены в большом количестве отбросы от разработок известкового ракущечника , которые, после укреплени  их предлагаемым способом, могли бьггь использованы дл  бетонных, каменных и штукатурных работ.In this connection, the author of the present invention proposes a method for strengthening the weak sands, which are almost always present on the site, in the area of the construction site, in the form of ground sand and waste from the development of limestone and so forth weak stone rocks. So, for example, in the area of the Bakansky wine storages, large quantities of waste products from the development of limestone shellfish were found, which, after being strengthened by the proposed method, could be used for concrete, stone and plastering.

Способ этот заключаетс  в следующем . Слабый грунтовой песок или известн ковые отбросы, освобождённые вручную от крупныхThis method is as follows. Weak dirt sand or limestone debris manually released from large

камней, тщательно смешивают без добавлени  воды с цементом, вз тым в количестве от веса песка и мелкого щебн , окучивают и оставл ют в течение нескольких дней дл  вызревани .stones, mix thoroughly without adding water with cement, taken in an amount by weight of sand and fine rubble, are spud and left to mature for several days.

Срок вызревани  зависит от естественной вла1жности песка и колеблетс  iBi пределах от 3 до 28 дней. Во врем  выдержки этого материала он должен быть защищён от вли ни  дожд , Ветра, солнца. Чем дольше, в указанных пределах, будет врем  выдержки, тем выше будет качество полученного таким способом песка.The maturation period depends on the natural moisture of the sand and varies between iBi from 3 to 28 days. During the aging of this material it must be protected from the influence of rain, wind, sun. The longer, within the specified limits, the exposure time will be, the higher will be the quality of the sand obtained in this way.

После такой выдержки песок поступает дл  замеса бетона или дл  других строительных работ.After this exposure, the sand enters to knead the concrete or other construction work.

Произведённые испытани  различных образцов (кубиков - на сжатие и восьмерок - на разрыв), изготовленных из полученного предлагаемым способом песка и щебн , показывают , что при составе раствора 1 :3 и при цементе марки 300 образцы дали через 28 дней Вре№ 64272- 2 -Testing of various samples (cubes - for compression and eights - for breaking) made from the sand and rubble produced by the proposed method show that with a mortar composition of 1: 3 and with a cement grade of 300, samples were given after 28 days Time No. 64272-2 -

менное сопротивление на сжатие отличающийс  тем, что изведо 185 кг/см а на разрыв - до стн ковый песок смешивают с ча22 ,5 кг/см.стъю предназначенного дл  замесаThe compressive resistance is different in that it is produced 185 kg / cm and the tear is mixed with cha22, 5 kg / cm stitch intended for kneading.

Предмет изобретени нее трёх суток в услови х, не доСпособ изготовлени  растворов и го смешивают с остальными собетонов на известн ковом песке, ставл ющими замеса ,The subject of the invention for three days under the conditions that are not available for the preparation of solutions and go is mixed with the rest of the mixture on limestone sand, which makes the mixture,
